Caller ID not working on incoming calls to line 1 of 4

I have four business lines, all of which have caller ID enabled. For about a year caller ID on line 1 has not worked. When I receive a call, it doesn't give the phone number or any sort of message about the incoming caller. I've tried resetting the modem, restarting the phones, etc, but caller ID still doesn't work for line 1. It works for all other lines, and I've double checked to make sure it's still activated on line 1.

Hello, @user_6677f4 Welcome to our Comcast Business support Forum page. Very sorry to hear that one of your four lines is not showing caller ID on incoming calls. I can imagine that would be very frustrating. Let's take a closer look. Please send us a direct message with your business name, address, and your name to assist!


To send a Direct Message:


Ensure you are logged in


Click the "Direct Messaging" icon or


Click the "New message" (pencil and paper) icon


The "To:" line prompts you to "Type the name of a person". Instead, type "Comcast Business" there.


 - As you are typing a drop-down list appears. Select "Comcast Business" from that list.


 - An "Comcast Business" graphic replaces the "To:" line.


 Type your message in the text area near the bottom of the window
